Yes!

...
repeat with i = 1 to the num of controls ## of cd x of stack y
  put the name of control i & TAB & the layer of control i & CR After tLayerList
end repeat
delete char -1 of tLayerList
## do something with tLayerList :-)
## field "name of field" TAB 1
## button "othe button" TAB 2
## etc...
...

Beware of DataGrids! :-D

Of course you need to be careful with objects in groups!
